Furthermore, as regards what is said by Euripides about the gods, ordinary folk too hold the same opinion. For the sentence— Whoe'er of mortals, sinning day by day, Deemeth the gods are blind to his misdeeds, Thinks evil thoughts and thinking thus is caught When Justice, haply, has some leisure time— is matched by the sentence commonly quoted: The mills of God grind slowly, but they grind exceeding small [ὀψὲ θεῶν ἀλέουσι μύλοι, ἀλέουσι δὲ λεπτά]— for the difference is only in the metre.
